NOTES:
1. Rewrite the INVC1 register after the PRC1 bit in the PRCR register is set to "1" (write enable).
The timers A1, A2, A4, and B2 must be stopped during rewrite.
2. The following table lists how the INV11 bit setting works.
Item
Mode
TA11, TA21 and TA41 Registers Not used
INV01 and INV00 Bit
in the INVC0 Register
INV13 Bit
3. When the INV06 bit in the INVC0 registser is set to "1" (sawtooth wave modulation mode), set the
INV11 bit to "0". Also, when the INV11 bit is set to "0", set the PWCON bit in the TB2SC register to
"0" (Timer B2 counter underflows).
4. The INV13 bit setting is enabled only when the INV06 bit is set to "0" (Triangular wave modulation
mode) and the INV11 bit to "1".
5. If the following conditions are all met, set the INV16 bit to "1".
• The INV15 bit is set to "0"
• The Dij bit (i=U, V or W, j=0, 1) and DiBj bit always have different values when the INV03 bit in
the INVC0 register is set to "1". (The positive-phase and negative-phase outputs always provide
opposite level signals.)
If the above conditions are not met, set the INV16 bit to "0".
